The recently reunited Stone Temple Pilots can add a full-fledged summer amphitheater tour to its previously announced U.S. festival dates, Billboard.com has learned.

Details are still coming together, but a source close to the alt-rock band says STP will play more than 50 shed dates this summer and into fall, beginning with the Rock on the Range festival on May 17-18 at Columbus, Ohio´s Columbus Crew Stadium.

Among the handful of other STP dates already announced are May 23 at the Indianapolis Motor Speedway as part of the Indy 500 and the 2008 Edgefest on July 12 in Toronto.

Further details about STP´s upcoming tour will be announced during an April 7 press conference at the Harry Houdini Estate in Los Angeles. Sources say that Los Angeles-based Live Nation will produce many dates on the upcoming trek. It is still unclear whether or not the band will record new material.

Rock on the Range will be Stone Temple Pilots´ first show since 2002. Scott Weiland is about to conclude a European tour with his post-STP band Velvet Revolver, but he and drummer Matt Sorum have taken their feud public, casting the outfit´s future into doubt.

STP broke up in late 2002; the band´s last album was the previous year´s "Shangri-La Dee Da." In 2002, the rock act grossed nearly $1.3 million from 13 concerts that drew approximately 42,000 concertgoers.
